In most states and some county and local jurisdictions, the Lessor is required to pay sales and/or use taxes on each monthly payment. Because the lease payment was calculated in advance, and these rates change from time to time, this amount is billed separately. In certain states, the full amount of taxes is due at the inception of the lease, and the responsibility to do so falls on the Lessor. In these situations, the tax is added to the equipment cost to calculate the monthly payment.
